Solar energy, an environment friendly energy source, is highly promoted by the state. BERSN direct current low pressure sodium ballast, operated in 24V direct current supply, can drive directly the low pressure sodium lamps of 18W、26W、35W、36W、55W、66W、90W、91W. Generally , to drive the vapour discharge lamps and other high efficiency light source, power supply converting gear is indispensable, and the consumption is large. However, BESN electronic low pressure sodium ballast overcomes such disadvantages.  Thus, in solar lighting system, it insures the best illumination from the most efficient light source .It also extends the lighting hours, and lowers the cost of the lighting system.

 solar garden lights : low pressure sodium lamp of 12V , 18W、26W are available.
 solar sideway lights( 2m-4m in height): low pressure sodium lamp of 24V, 35W、36W are available.
solar street lights(5m-8m in height): low pressure sodium lamp of 24V, 55W、66W are available.
Solar high mast lights: low pressure sodium lamp of 24V, 90W、91W are available.
Tunnel lights: low pressure sodium lamp from 35W to 90W, direct current or alternating current supply are available

 Low pressure sodium lamp is high in efficiency (200lm/W), long in lifespan, and can seldom be affected by ambient temperature. It is the optimum light source and appliance system to match the  solar lighting system. We can manufacture customized electronic low pressure sodium ballast( dimmable ). The light is dimmable according to environment lighting requirement. Thus the electricity output from the battery pile is greatly saved, while the lighting hours extended, the system cost lowered. It accelerates the development of solar lighting system in China, and brings profit to our customers as well as making contribution to China environment friendly lighting project.
